Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

That might work - I have never had the chance to poke around on a Linux system with a Bluetooth chip in it, but just as a note, grepping for "bluetooth" would limit you to that exact string, keeping in mind that UNIX and Linux are terribly case-sensitive.

Here is a not-so-wise question. OK --- Lets say I come to a PC, which runs Linux and I would like to know if the PC has bluetooth capabilities --- what command should I commit in the terminal?

I tried something like:

Code:

lspci | grep bluetooth

Is the above the right thing to see if the teeth are blue?

What version/distro of Linux? You can type in /etc/init.d/bluetooth status (if you're root), and see what it returns. You can do a "ps -ef | grep blue" to see if the bluez stack is running...look at the KDE/Gnome desktop to see if you've got the bluetooth icon in the systray.

Under SYSTEM SETTINGS >> ADVANCE >> HARDWARE, I see BlueZ solely listed as Bluetooth Management Backend.

Despite all these I do not see the icon in the systray. My phone (SAMSUNG E250) cannot even feel the systems bluetooth.

I have installed loads of blue-related software from Synaptic.

Ok..your bluetooth is running. The LSPCI won't show anything for bluetooth, since that just lists some of your hardware devices. Since you're running KDE, go to the application menu, and type 'blue' in the search-box. Run the KDE Bluetooth Monitor...the icon will appear.

I could not get KDE Bluetooth Monitor, but instead I got Bluetooth File Transfering, and Kde4bluetooth. The former gave me a icon in the systray, but it only says its purpose when you hover over the icon --- clicking the icon does not help. Kde4bluetooth, I understand has its own issues at the moment, it is non-responsive on my system
